Why Tinker?

Far from me to question the methods and wisdom of Mr.Guardiola but why the recent tinkering?

I can understand the desire or need to change the team around at the beginning of a season, to help find the right formula, but why do it in two of the most important games at the rear end of the season? It maybe an attempt to unnerve or outfox the opposition, but at what cost?

Against Real Madrid Dani Alves played on the right of a front three. I can understand that with Puyol at right back the defending duties are covered and with Alves further forward his pace could be used as a more attacking option......but he was too eager and caught offside too many times. Another time (early season?) and I am sure the tactic would work, but used as a one off it threatened to unbalance the team putting some players in unfamiliar positions.

Against Inter Milan, in the home leg, Maxwell was played on the left of a front three. Being the only outfield player NOT to have scored for Barca this season it hardly sends the opposition into a worrying state of mind. Would the same have been said if either Bojan or Henry started in that position. As it is, I believe Maxwell to have been one of the most consistent players this season, but it is unfair to expect him to carry that attacking threat in such a big game.

We beat Real Madrid but lost to Inter so it's 50-50 on the tinkering stakes.

Not being privy to the background to these decisions there maybe very fair reasoning for making them..........but as a fan they are bemusing when we are looking for consistency and success.
